ABSTRACT
The following calculations are mostly for mortality in the age range of 40-79 years, since death at a later age is, for those who reach it, inevitable, but many deaths in this range are not. Most of the avoidable person-years of life lost because of obesity are in this age range: each avertable death after the age of 80 causes relatively few years of life to be lost, and obesity causes few deaths before the age of 40.
